I have to install a ground stake to mount one of these purple Martin nesting gourd sets. About 15’ tall, lightweight aluminum.

Instructions say the hole to set the ground stake should be 36” deep, 12” wide, square aluminum ground stake projects 2’ above the ground, pole base slides down over it. I’ve put up several of these things in the past, but the last one was 12 years back.

This weekend the highs are forecast to be in the 50’s, lows in the 30’s. Obviously the ground stake has to set exactly vertical.

How long does it take Quickcrete to set at lower temperatures?

Tks.
